AWS Transfer Family supports self-signed TLS certificates, 3DES encryption for sending AS2 messages



AWS Transfer Family now provides you with the option to import and use a trading partner’s public, self-signed TLS certificate for sending Applicability Statement 2 (AS2) messages to their server over HTTPS. Additionally, you can now choose to encrypt messages sent to your partner’s server using the 3DES cipher. By default, AS2 connectors will encrypt messages with the AES128 cipher unless you select 3DES for purposes of backwards compatibility with your partner’s existing AS2 implementation. These capabilities add to AWS Transfer Family’s existing list of AS2 interoperability features and enable you to reliably connect with trading partners that require these specific security configurations. Support for self-signed TLS certificates and option to enable 3DES encryption when sending AS2 messages is available in all AWS Regions where the [AWS Transfer Family service is available]( To get started with Transfer Family’s AS2 capabilities, take the [self-paced workshop]( or deploy the [AS2 demo template](
